From 7059fa6ff8be2b97c36beab506e683f94cd71394 Mon Sep 17 00:00:00 2001 From: Allan Jude Date: Sat, 18 Jul 2015 18:49:44 +0000 Subject: [PATCH] Add support for two workarounds for known issues booting GPT in legacy mode on some hardware For Lenovo laptops with buggy bios (x220, t420, t520): Write the 0xee entry into the second slot in the pmbr instead of the first For some Dell and HP models: The BIOS gives a warning message when booting in legacy mode from a GPT partitioned disk where the 0xee partition in the pmbr is not flagged active For models known to have this problem, mark the pmbr active during installation Use smbios data to identify machines known to be affected by any of the above, and offer the user the option to apply the workaround In bsdinstall's ufs auto mode (autopart partition wizard): Allow users to select which type of partition table to use Keep current defaults: MBR for BIOS, GPT for UEFI This allows users to choose GPT for legacy boot if they wish PR: 184910 PR: 194359 Reviewed by: Michael Dexter Approved by: marcel MFC after: 3 days X-MFC-With: r285594 Relnotes: yes Sponsored by: ScaleEngine Inc.
